WINDOW ADJUSTER 3 Sheets-Sheet 3 Filed Nov. 28, 1951 United States Patent WINDOW ADJUSTER William J. Paulussen, NutleyfN. 1. Application November '28, 1951, Se'rialNo. 258,550 20 Claims. (61. -292 261) This invention relatesto a window adjusterfor-holding a window-sash in any-position to wh-ich it may 'be moved.

For a great many years window sashes have been mounted and carried in frameswithin'which channel spaces'have been "provided to receive weights-madeof cast iron andfrom 10 to 12 inches long and-an inch and a half (1%) in diameter, these weights "being attached to cords which are passed over =pulleys in the upper part of the-window frame and attached toa window sash through theme'dium'of a groove terminating in a'recess'in the"sash'to-receive a knot at'the end of the cord weight. .With this construction when a sash cord breaks as they frequently do, in som'e -window of a house or apartmennit'isahard job to p'ut'in a new sash cord. Asa matter of'fact, appl-icantThas found that very-few men' know how to do this,-especially in an expeditious and propermanner. To take out the lower sash a side strip which is usually nailed onto the window frame,'must be removed and thesa'sh withdrawn. Then a string with a small weight-attached to-one end must be passed over -"the pulley atthe top of the sash slideway and this weighted end of the string attached to a new sashcord and the samepulled up over the pulley and this end knotted and placedin the sash recess while the other end is attached to the sash Weight. To get this 'cord the right length, so that the sash may be moved throughout its range of movement requires some=experience. Toireplace acord for the top sash is mu'chharder, as'sideyguide strips must be taken out and usuallythese are installed in rather tight fits. To 'make'these 'repair jobs'therefore requires quite some time even-for 'on'e' that"really knows how to do it. I

It is therefore they principal object of 'mypresentjinvention to provide a new and simple-device which may be easily and quickly installed "on window sashes already in existence. A further'object *of my invention is to provide a construction which can be utilized 'in newly constructed houses at a great savingcompared with the cost'of the old window constructions :as will be seen from the description which follows:

Referring now to the details wherein like numbers refer to corresponding'parts, 1 represents generally an oldstyle of window frame having an upper window sash 2 and a'l'ower window sash 3 each haviugglass pane 4 whichis shown in one piece but which may be composed of a plurality of individual panes held in place by the usual putty means. For use with the Window sashes 2and 3to take the place of the sash cords, weights, pulleys, etc., lutilize a small, simple casing 5 of suitable metalsuch as aluminum. The casing has an upturned portion fiat'one end and an upturned portion 7 atthe other end with a turned up side 8-while there is no upturned edge on the side 9. The casing 5 has two holes therein 'to receive mounting screws and I1. .Positioned within the leasing 5 is a movable member or plunger 12 'having'an inturned loop forming a cam surface 13. The lower end of the plunger 12 which passes through a slot in the end 7 of the casing is bent over at 1'4 for the=purpose to be presently described. "Positioned within the casing "5 is a roller preferably of a disc type of a suitable material such as gum wood'or maplealthough this disc roller may be made of a satisfactory plastic-or other material the main thing being that it'haslongwearing-properties. As shown in Figure 4 'the roller 15 rests-on a smooth part of the screw 11 so that the vertical axis through the center. of the roller and zthe center of the screw are displaced as shown by the drawing whereby the roller will of its own inertia be again'stithe side piece 16 of the Window frame. Normally as'shown inFigures 2 and 4, the weight of the plunger 12 holds the cam surface '13 thereof against the roller and in continuous contact with the window casing :16 and any effort-to move the sash, whether it be the lower or upper one, will bejprevented by'the gripping of the roller between the cam surface 13 and the window'frame-member 16. To move either of'the sashes'all'that'is necessaryto do is to push upward on the: end 14- of -the plunger 12 and to free the roller 15 SOthatthesashmay be moved to an open position. When lihlSzlJOSHlOIlfiSTached the'plunger 12 is released and the roller moved back to holding position of the sash at the desired point.

.lna-F-rgure 7 the construction is very much the same as :heretofore described except that a pivoted lever 13 used between the'cam surface 13 and the roller 15, the-screw 11 ibemg moved to the left so that the roller 15 *runson the end 7 of the casing.

In-Figures 8-:11 inclusive, the adjuster has the casing 5 set Into aside therein.

5. Also-therplunger 12 has its arm 14 extending toutwardly through the side piece of the window sash whereby-1t maybe engaged by the hand of by r ivet.24 to'the side of the casing acts to hold the-lever 20 in normal-engagement with the roller 15 keeping it in "contact with the side of the Window frame. The operation of this form of the invention isthe same as in the previous figuresreferred to.

In the form of construction shown in Figures 13-17-a lever is fastened as by a-screw 26in the top of the recess '27 cut in-theside of the window sash. The opposite end of the lever passes outwardly through the sash and has a downwardly bent end 28 which is positioned over and free from the glass 29 carried by the sash. The lever is formed with two cam surfaces 30 and 31 which meet at a point 32 approximately midway of the length of the lever. At this central point an adjusting screw 33 is utilized to give the required tension to a spring 34 which is utilized to normally hold the cam surface 31 of the lever 25 against the roller 15a which is located at the bottom of the recess.27. Pivotally mounted by a screw 35 is a bar 36 having an inturned end 37 that is adapted to engage a roller 151) which is positioned on the cam surface 30 of the lever 25. The bar 36 has an opening 38 therein to receive a key 39 utilized for moving the bar 36 about the pivot 35 for the purpose to be presently described. Positioned over the bar 36 which fits in a recess 40 in the sash, is a plate 41 held in place by screws 42. Plate 41 has a slot 43 therein to allow movement of the key 39.

In the operation of this structure it will be seen that with the bar 36 in the position shown in Figure 15 the roller 15b is in gripping or locking position with the inner edge of the window casing. To move the sash to open position the key 39 is inserted in the slot 38 and the bar 36 moved upwardly to engage the roller 15b as shown in Figure 13, whence it can be lifted to release position. Then by preferably pulling outwardly on the end 28 of the lever 25, the sash may be moved to an open position. On releasing the lever 25 and withdrawing the force from the window sash the roller 15a will move up to the dotted position shown in Figure 15 thereby locking the sash in the position desired and on returning the bar 36 to the position shown in Figure 15, the roller 15b will move back to locking position thereby giving a double lock on the window sash. To release the sash so that it can be moved to closed position from this double lock, the bar 36 should be moved to the upper part of the recess 40 which will move the roller 15b to release position, then by an upward push on the lever 25 and then an outward pull on the downwardly extending end 28 of the lever 25 to move it into the position shown in Figure 15, the roller 15a will be released and drop down to the idle position at the bottom of the recess 27.

From the foregoing description it will be seen that I have provided a very simple and relatively inexpensive means for controlling the operation of window sashes and since there is relatively nothing to break or get out of order, the repair work required is reduced to a minimum, and if any repairs do it in a very short period of time. I have found from tests, that the device described herein will last a long time and give excellent results in the adjustment of window sashes.

I claim:

1. A window adjuster comprising a casing having one edge open, means for fastening the casing to a vertical side of a window sash with the open edge a short distance away from the adjacent side window frame, said casing carrying a single piece plunger having an internal loop within the casing forming a single cam surface, the plunger having one end extending outside the casing when mounted on the lower portion of the side of a window sash so the plunger can be raised and a roller of suitable material within the casing positioned so the cam surface of the plunger will engage the roller and cause it to lock the sash to the side of the window frame.

2. A window adjuster as set forth in claim 1 further defined in that the window sash may be lowered from open position by pushing upwardly on the extending end of the plunger whereby the roller is released from its gripping position on the window frame and the sash lowered.

3. A window adjuster as set forth in claim 1 further defined in that the plunger has a rectangular cross section with the long dimension part of the rectangular shaped plunger engaging the outer surface of the roller which is disc shaped, the width of the disc being substantially the same as the width of the plunger.
